Disasters in Bangladesh

This paper deals with various types of natural disasters which occur very frequently in Bangladesh. Disaster can occur at any time, in any place, in any dimension, and may owe as much to the circumstances as to the scale of the event. With the exception of the man-made disaster of war, famine, fire, pollution, accident and civil strife, the worst disasters follow natural events.Bangladesh is widely known as a land of natural disasters and is highly vulnerable to flood, cyclone and river erosion. By the effects of these disasters the country is now permanently in distress. These disasters have become a regular phenomenon and cause suffering to millions of people of the country since many decades. Besides, it also focuses on policy options concerning disaster management.

Seismic hazard analysis for a spatial linearly distributed system

The models currently used in the seismic evaluation of important projects, microzoning and seismic zonation are all for site. Although seismic hazard analysis have been done for many sites in seismic zonation and microzoning, relationship among sites is not considered in the final results. Studies show that it is impossible to get total hazard for specific area from the results of the hazard analysis of sites. So, when we consider the total seismic hazard of a specific spatial distributed system, methods for site are not enough. Author discussed the relation and the difference between system hazard and segments hazard which form the system and proposed a seismic hazard analysis model taking spatial linear distributed series and parallel system as an example. In aseismic design and earthquake disaster prevention decision, not only the seismic hazard of segments of the system but also the total seismic hazard of the system should be considered. The Chinese version of this paper appeared in the Chinese edition ofActa Seismologica Sinica,15, 347–352, 1993.

地震灾害风险评估及减灾策略研究——以贵州罗甸县为例

为探究贵州省地震灾害风险薄弱环节，减轻地震灾害风险，以贵州省罗甸县为示范，采用地震危险性概率分析方法对各乡镇进行危险性分析，开展地震灾害承灾体现场抽样调查，通过层次分析法和问卷调查的方式，首次构建乡镇级别的地震灾害风险和减灾能力指标体系，评估各乡镇地震灾害综合指数和程度，计算各乡镇地震灾害风险指数，确定红水河镇为高风险区、罗悃镇为中风险区、木引等7个乡镇为低风险区，并从建筑物设防、地震地质灾害及水库地震等角度剖析罗甸县地震灾害特点，从农村危房改造、移民搬迁、地质灾害防护及交通等方面提出减小地震灾害风险的建议。     

河北省雷电灾害事件特征分析

为了解河北省雷电灾害事件的时空分布、行业分布、经济损失及人员伤亡等,对2006—2017年(不包括2013、2016年)河北省雷电灾害事件资料进行统计分析。结果表明:河北省近10 a雷电灾害事件呈逐年波动递减的趋势,主要发生在6—8月,占全年雷电灾害事件总数的81.34%,唐山、保定和石家庄市为雷电灾害事件的高发区。雷电灾害事件最为严重的是电力行业达382起,人员伤亡事故主要发生在乡村。     

重庆市自然灾害管理综合信息系统研究

从重庆市自然灾害情况及其信息管理现状分析入手,构建了重庆市自然灾害管理信息系统目标、整体设计和界面开发。重庆市自然灾害管理信息系统主要由4个模块组成：自然灾害数据库模块、远程通信管理模块、应用分析模型库模块及决策支持模块,它们通过一定的数据接口连结,在GIS平台上成为一体化系统,对重庆市自然灾害进行有效地管理和监测,从而减少自然灾害带来的经济损失。
